“…However, the FEA method has not been adopted widely for this purpose to date because of the large amount of computations and high level of finite model fidelity required. For these reasons FEA is traditionally used in the detailed design stages of the development process in order to improve solution synthesis once a preferred design is fully defined [Qian et al (2001); Gelgele (2006); Firat (2007); Kajtaz (2012)]. The current FEA-based approaches for evaluation of load-bearing structural design concepts are typically ad hoc adaptations of the conventional FEA application in the conceptualization phase environment whereby the use of FEA closely resembles the subsequent product validation phase where FEA is traditionally used [Sapuana et al (2005); Davoodi et al (2011)].…”

The research presented in this paper has extended the substructuring technique into the nonlinear domain in order to apply the finite element analysis (FEA) method to complex nonlinear structural design problems in the conceptual design stage. As conventional FE models based on substructures allow only linear analysis, it was necessary in this research to introduce a new algorithm capable of linearizing nonlinear structural problems with sufficient accuracy in order to enable evaluation of engineering design concepts in a more objective and rigorous manner in the early stages of design. The developed method was implemented within a commercial FE solver, and validated using a select number of case studies. The results obtained for the two sample solutions indicate that the new method has achieved an improvement in accuracy of 90% and 98% respectively compared to the conventional FE-based approach applied to the same class of design problems.

“…However, the utilisation of FEA in the conceptual design phase has been very infrequent and partially effective to date because of large amount of computations and of high level of finite model fidelity that were required. The FEA is traditionally used in the later validation phase of the development process [24,25,26,27] to improve solution synthesis once a preferred design is fully defined. Despite the mentioned shortcomings and their lack of applicability in the conceptualisation phase, the FEA based approaches are sometimes the only feasible alternatives capable of evaluating load-bearing structures due to high complexity of the engineering design concepts.…”

The paper presents a novel approach to comparative evaluation of engineering design concepts that exhibit non-linear structural behaviour under load. The developed method has extended the substructures technique in order to apply the Finite Element Analysis (FEA) method to complex non-linear structural problems in the conceptual design phase. As conventional FE models based on substructures allow only linear analysis, it was necessary in this research to introduce a new algorithm capable of linearizing non-linear structural problems with sufficient accuracy in order to enable comparative evaluation of design concepts relative to each other under the given constraints and loading conditions. A comparative study with respect to model size, efficiency, accuracy and confidence was performed to validate the developed method. Obtained results indicate significant improvement over more traditional approaches to applying FEA in the conceptual design phase. The improvements achieved using the developed method compared to the traditional FE based approach are superior by a factor of 2.7 in efficiency and by a factor of 4.5 in confidence while not sacrificing the optimality of the solutions.
